Description
monitored in a timely manner. If
a battery overtemperature alarm
is detected, the charging current
limit decreases to 0.03 CA.
Battery charging stops if a
battery overtemperature
protection alarm (when the
temperature reaches the high
temperature threshold plus 3° C)
is generated.
Single batt. float chg. voltage
deviation alarm thres. (%) and
Single batt. dis. voltage
deviation alarm thres. (%) are
used to check whether the cells in
each battery string have the same
charge voltage and discharge
voltage. When a value exceeds
the specified range, an alarm is
generated.
The calculation formula is
(Charge/Discharge voltage –
Average voltage)/Average
voltage x 100%.
After this function is enabled, an
alarm is generated if the
configured battery capacity
exceeds the charging capacity of
the rack.
In battery mode, the UPS can
automatically power off
according to the preset shutdown
delay time. If the parameter is
disabled, this function is not
available.
An alarm is generated if this
parameter is set to Enable and
the backup time is less than the
warning threshold.
An alarm is generated if this
parameter is set to Enable and
the remaining capacity is less
than the warning threshold.
If this parameter is set to Enable,
the intelligent battery hibernation
function is enabled.
If an output dry contact is set to
Low battery SOC, and the
